hello everyone , sorry for the long post , I have a tank that is running for 4 months , but there is a problem with my sps corals , they are not growing and some easy species are start to dying . coloraiton is fine , i dont have any tissue lost expect caliendrum and birdsnest , evern my acroporas are fine , but they dont have grow out tips. I am doing water twice in a month and doing weekly tests.
my parameters are:
SG 1026
KH 8.0
CA 440
MG 1335
PO4 0.11
NO3 5
my lighting is 6*54watt t5 , i bought it second hand , the t5s were already on it and the man i bought the fixture said ' t5s are 3 months old, i can prove it ' .
combination is 3*blueplus, 1*coralplus 1*actinic 1*purple plus.
I have mp40 and 2*hydor koralia 3g (5000 liters per hour )
also i have a small cyano problem , just on my rocks not on the sand.
my lps corals doing great they are growing , opening well , but i cant say the same things for my sps corals. what can be my problem , i do also have coraline all over my rocks but still i dont see any consumption on kh mg and ca.
